Abstract

Lingual vibrotactile thresholds were obtained from four groups of subjects using a different tongue-clamping procedure with each group. The four experimental conditions were designed to assess the effect on threshold sensitivity, across five frequencies, which results when using a free-surround clamping disk. Data indicated that the free-surround clamping disk used limits stimulus spread and results in greater threshold sensitivity than that obtained for conditions which do not employ this procedure. Findings supported the view that pressure receptors in the anterior dorsal surface of the tongue are selectively responsive to differences in vibratory rates of mechanical displacement. © 1977, The Psychonomic Society, Inc..
